CAR-AXLE LUBRICATO R.

SPECIFICATION forming part of Letters Patent. No. 389,372, datedSeptemberll, 1888.

Application riled December 16, 1887. Serial No. 959.1%. (No model.)

To aZZ whom it may concern.-

Be it known that I, RUDOLPH FAAS, a citizen of the United States ofAmerica, residing in the city of Chicago, county of Cook, and State ofIllinois, have invented a new and use ful device and Improvement inCar-Axle Lubrieators, of which the following is the specifieation.

The objects of my invention are to more perfectly confine the lubricantin the car axle box,protectitfrom accumulations ofsand, dust, or othergritty substances, and to add to the strength and durability of theroller. I attain these objects by the mechanism illustrated in theaccompanying drawings, in which Figure l is a vertical cross-section ofa caraxle box, showing my device therein and its relation to thecar-axle journal. Fig. 2 is a sectional view on line 2, Fig. 1. Fig. 3is a plan view of the frame of the device with the roller removed.

Stmilarletters refer tosi milar parts through out the drawings.

In the construction of my device I use two bars, I) D", which, joinedtogether by two bolts, a b, and flat rubbing-bar d, constitute the frameof my device, on which is journaled the roller E.

Underneath the frame above mentioned I place a steel spring, F, which isformed of one piece of steel wire bent in the form of a bow and havingthe two ends coiled and affixed to the bolt b, which elevates the frameand roller and causes it to engage with the car-axle iour nal A, keepingit continuously lubricated.

For a more complete description of the method of construction of mylubricating de vice I refer to my application filed in the Patent OfficeAugust 11, 1887, for which Letters Patent were issued on the 27th day ofDecenr ber, A. D. 1887, hearing No. 375,700.

As an additional improvement thereto and to increase the efficiency ofthe device above patented, I attach to the upper side of the apron h onthe bar I) or to the bar D (or to both when it may best suit my purpose)a vertical thin brass plate or shield, H, which is out circular in formon its upper edge, so as to conform with the exposed segment of the jour nal A, and its closely to the same.

In the usual method ot' eonstruetion of the car axle box B the rear endthereof and occasionally both ends contain an aperture or open ingthrough which dust and sand enter the journal box and are deposited onthe car-axle journal A and in the lubricating material. The brass plateor shield H above described is intended to cover the apertures inthejournal-box A, whether in one or both ends of the same, and thus moreeffectually conlines and protects the lubricant as well as the car axlejournal. To the axle X of the roller E, in addition to the flanges Z Zon the end of the same, I place the two flanges or washers g g, ofbrass, (to increase the durability and strength of the roller.) On thespool thus constructed l wind canvas, cloth, felt or other porousmaterial to form the roller of my improved device.

Bei ngaware thatheretofore lubricators have been constructed by havingrollers of various kinds engage with the car-axlejournal, do not in thisspecil'ication claim such a combiua lion, broadly; but

\Vhat [do claim as new, and desire to secure by Letters Patent, is-

In the construction of acar-axle-lubricating device in which a rollerengages with the earaxlejournal, the frame in which the roller isjournaled having on its sides and projecting vertically a thin brassplate or disk, so as to cover or close the apertures in the sides of thecar-axle box, as and for the purpose above specified.
